Not clear whether West System or Epotec products are better suited to piano work. It appears that the Epotec #337 may offer increased strength/hardness over their #301. Anyone ever play around with both or all three of these products? They are quite different products. Epotek #301 is quite thin and is probably suitable for applications that require penetration although what the company touts about it is its optical clarity. Typically, this is not a characteristic of high importance with the piano work in which epoxies are most often used. Had I been able to get small samples from the company I would have experimented with it and reported on it in my recent articles. But I'd have had to buy more than I wanted for testing and time was running short. As is, you'll have to go on others experience. Gougeon Bros. products have a long history of successful application on wood and wood structures ranging from boats to wind turbine blades to wooden bridges. As do other wood-specific WEST epoxies such as System Three and MAS. (The acronym WEST stands for Wood Epoxy Saturation Technique and is not specific to epoxies only from Gougeon Bros. At least it wasn't the last I heard--I vaguely recall a lawsuit over this some years back--I think Gougeon lost.) One day I still might experiment with Epotek products, but for the most part I am quite happy with those wood-specific products I use now: Gougeon Bros. WEST products, System Three and MAS. They are formulated for and are intended to be used with wood. They are intended to mixed with various fillers. They work. Del
